The Eight Burning Books of Khorne are the greatest source of knowledge concerning the dread Daemonic servants of the Chaos God Khorne, the god of war and murder. Bound in brass and etched in fresh blood, each is said to decree the eight unholy aspects of the Lord of Skulls and name his Daemons.[1b]
These grimoires are much searched for by renegade wizards, for knowledge of a Daemon's True Name is believed to render it servile to mortal command. Such an acquisition is not easily made for the Burning Books are scattered across existence and each has its own terrifying and bloodthirsty guardian.[1b]
The Bloodthirster Hellgrin led an army that attempted to retake one of the books from its resting place in the Annulii Mountains in 570 IC. He was vanquished by a High Elf army commanded by the High Elf Archmage Calahdris.[1a]
